I have some amps from a previous build that I will reuse. I’ll post questions in the appropriate areas, but I’m looking to do a quite loud system for low bucks.I’ve currently got an Orion HCCA D2400 Mono, good for (RMS):•    4 Ohms: 425 watts x 1 chan.•    2 Ohms: 800 watts x 1 chan.•    1 Ohm: 1200 watts x 1 chan.As well as an Infinity Reference 7540a 4 channel, good for (RMS):•    4 Ohms: 111 watts x 4 chan.•    2 Ohms: 139 watts x 4 chan.•    4 Ohm: 278 watts x 2 chan.Additionally, though I don’t see that I’ll need it, a very old, but perfectly functional Phoenix Gold XS2300 that from memory has a low-pass at 80HZ, but will also do full range, good for (RMS):•    4 Ohms: 75 watts x 2 chan.•    2 Ohms: 150 watts x 2 chan.•    4 Ohm: 300 watts x 1 chan.So I’ve got plenty of juice!Subs:I don’t want to take up much trunk space, so I think I’ll probably stick with a single 12, or maybe 2 10s if I can build very efficient and small box. Carpentry is not a problem.I need help with sub choices, I’ll probably hunt craigslist for the used discounts. The trick is, I’d like to make the most out of that Orion and get something that will match nicely. I’m looking for an inexpensive 12 that is most likely dual voice-coil 2 Ohm each that can handle 1000 watts. Or, possibly two 10s that I can wire to 1 Ohm, but they need to be happy with a small enclosure.Any thoughts? Is this impossible?General:Unfortunately, I need to buy an LC7i or equivalent to interface with my stock system. The stock system also controls the HVAC and some car settings. It’s got a weird, proprietary, optical link system, so simply replacing the head unit isn’t possible. (Jaguar) I’ll do some further research, but I believe I need to sum at least three speakers per side to get the full range signal. I do know that there is a bass drop when I turn up the current system, so the Bass Restoration will be necessary.I’d love to run a PPI DEQ8 or the MiniDSP2x8 or something like that, but it’s out of the budget currently.Speakers:I have no idea if I want to find a decent bargain 6.5 + tweet component set (used is fine) or try to build something with the pro audio stuff. I like the idea of pro-audio in that it is built to be loud and when installed well, sounds pretty dang good, but costs less than a budget component set (if I’m able to go active, but that would depend on me getting the MiniDSP, so it gets expensive again, but comes with a bunch of advantages)</blockquote>
